Why is it important for solar buildings to store solar heat? How do both passive and active solar homes do this?
This is important becuase without the ability to store heat, the buildings and homes would be cold on rainy days and at night. In a passive solar home, think insulation (masonary, stone, concrete) absorbs heat and sends it back into the room. In an active solar home, the heat can be stored either by filling a tank with liquid used to store the heat or rock bins can store heat under the building or home.
